WATER-PURIFIER.

To all whom it may concern:

Be it known that I, HERBERT CAssAR'D, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Water-Puriliers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specilication.

The present invention relates particularly to the class of purifiers inwhich there is a voltaic pile inclosed in the chamber or gland throughwhich the feed-Water I flows before entering the boiler, and the objectof the present invention is to provide 'a compact pile that shallpresent to the action of the water a large amount of surface with a Viewto securing the greatest efliciency combined with a compact and simpleconstruction.

To this end the invention consists of a voltaic pile having a spiral orcircuitous channel for the iiow of the water through or within the pile,as hereinafter fully described and set forth. p

In the accompanying drawings: Figure l is a vertical sectional view of a-feed-water purifier constructed according to the present invention.Fig. 2 is a longitudinal sectional View of the same taken through thepile. Fig. 3 is a detached perspective view of one of the plates of thepile. Figs. 4 and5 are respect-` ively longitudinal and transversesections of a modified embodiment of the invention; and Figs. 6 and 7illustratea construction of gland wherein there is an end inflow for thewater.

A is a cylinder constituting the purifier chamber, the same having aninlet pipe, a.,

entering through the side ot' the cylinder at the bottom, and an outletpipe, a', through the center of the head A. The outlet pipe, a', isenlarged for a short distance and a spiral spring B is incased in thisenlargment; the shoulder a2 in the pipe forms a seat for the upper endof the spring and the lower end of thespring bears against a plate F onthe top of the voltaic pile, C. The voltaic pile is built up of roundplates of zinc and copper, D and E, or other elements, which nearly fillthe inclosing cylinder A, space enough only beingleft within the shellaround the pile for it to be easily inserted. The cylinder has aninsulating lining, a3, and the pile rests on an insulating base plate,a4. The cap plate F has a central opening, f, and the end of the springD is seated in the groove around the' opening. The spring and cap plateoperate to compress the -pile and hold the plates thereof in contact.The plates of the voltaic pile are `made with a spiral opening, G,starting at the circumference as`at the point, g', (Fig. 3) and windingin toward the center of the-plate, Where the opening, ends as at g. Thisspiral opening may take any winding form within the plates, and theplates may be square or of any other shape; the essential feature beingthe channel for the flow of water from the perimeter of the pileintoward the center, or vice versa. Each plate also has one or more keyseats g3.

When the plates are set up to form a voltaic pile the openings, G, inthe several plates register with each other, and a bar, g4, of anysuitable insulating material, (lead even will ordinarily answer thepurpose,) itted in the line of key seats, locks the plates in position.

- A pile is thus formed with a convolute channel starting at thecircumference and terminating in the central Hue or opening, whichextends through the pile from end to end. This central flue registerswith the opening, f, in the cap plate F and the pile is placed in thecylinder A so that the inlet pipe, a., is opposite to thecircumferential entrance to the spiral or convolute channel. The Waterflowing through the purifier, enters from thel inlet pipe, a, and flowsthrough the spiral or convolute channel in the plates until it reachesthe center and thence through the center of the cap plate F, to theoutlet pipe a. The thin copper plates of the pile need not necessarilyhave the spiral opening, only the central hole, in which c ase theconvolute channel will be divided by the copper plates into a li-neofspiral channels.

In the modification illustrated by FigsA and 5 a water channel I is leftaround the pile between the same and the containing cylinder, this spacehowever being closed in at the top by the cap plate F which extends outto the Walls of the chamber. In this case the IOO plates D and E of thepile are set so that the spiral openings of contiguous plates will notregister except at the central part thereof, and the result is thatinstead of the pile having a convolute channel leading from thecircumference into the center, there is a central flue g5, extendingthrough the pile from end to end with numerous spiral channels leadingthereinto from the circumference; these spiral channels starting atdierent points on the outer face of the pile, according to the positiongiven the dierent plates in setting them in place. In this case thewater entering the purifier flows around the pile and in through thenumerous spiral channels to the center main channel, and then ont asbefore.

In the form illustrated by Figs. 6 and 7 the inflow pipe, a, is in thebottom of the puritier cylinder, and the voltaic pile, C, is supportedon a plate II, raised above the bottom of the cylinder. This plate has,near its edge, a slot, h, conforming in shape to the outer portion ofthe spiral channel, Gr, in the voltaic plates; and the voltaic plateswith their spiral openings in alignment, are placed on the supportingplate, I-I, so that the slot, h, in the plate, H, registers with thecorresponding portion of the spiral channel in the voltaic plates. Inthis case the intlowing Water enters the chamber beneath the plate H,and then passes through the/slot, h, into the spiral channel in thevoltaic pile and then out as in the form of the device rst described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a Water purifier, the combination of a casing with inlet andoutlet pipes, a voltaic pile having a channel leading from the perimeterto the center of the pipe and a cap plate having a central opening,substantially as and for the purpose set forth.

2. In a water purifier, the combination of a shell or casing havinginlet and outlet pipes, a voltaic pile havinga channel therethrough fromthe perimeter to the center, and a springpressed covering plate having acentral opening registering with the central opening of the pile,substantially as set forth.

3. In a Water-purifier, a voltaic pile having a central passagetherethrough and a channel leading from the perimeter to said centralpassage and a cap-plate having a central opening registering with saidcentral passage, substantially as specified. v

4. In a water-purifier, avoltaic pile having a central passagetherethrough and numerous transverse openings from the perimeter of thepile to said central passage and a cap-plate having a central openingregistering with said central passage, substantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
